Light in semi-cylinderElectricity and Magnetism Level 2
The refractive index of the air is \(1\).
a) The wavelength of light A in the glass is longer than that of light B in the glass.
b) If the monochromatic light A enters at point q instead of p, then it will totally be reflected internally.
c) If a light with a shorter wavelength than the monochromatic light A is entered at point p, then it will totally be reflected internally.
